BOMB THROWER.

Application filed March 2, 1923.

To aZZ whom t may conce/rn Be it known that I, WLADYsLAw MARO- WIEcKI, a citizen of Poland, residing at Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Bomb Throwers, of which the following is a specification.

This invention relates to improvements in bomb throwers, and it is the principal object of my invention to provide a device of this kind in form of a gun in which a grenade or shell adapted to be ejected from the gun by a spring controlled ejector mechanism, will impart to the bomb the necessary velocity as it is ejected from the gun.

In combination with the device having the above characteristics, the invention aims as a further object to provide a novel construction, combination and arrangement of parts.

In the accompanying drawings forming a material part of this invention:

Figure 1 is a top plan View of my improved bomb thrower constructed according to the present invention.

Figure 2 is a side view thereof. Figure 3 is a transverse section through the bomb thrower, along line 3 3 of Fig- 30 ure 1.

Figure 4 is a detail side elevation of a wheel.

Figure 5 is a top plan view upon the rear end of the bomb thrower, partly in section.

Figure 6 is a sectional side elevation of the ejector mechanism, the section being taken on line 6*@ of Figure 5.

Figure 7 is a detail view of a trigger mechanism.

Figure 8 is a longitudinal section through the gun barrel.

Figure 9 is an end View of vthe grenade or shell carriage, and

Figure 10 is a side view thereof.

The bomb thrower comprises in the main a gun barrel 10 mounted on a carriage 11 resting on wheels 12. The barrel 10 is held in place upon the carriage 11 between vertical standards 13 securely fastened with their foot parts 14 to the carriage and carrying at their upper, bent ends two clamping members 15 and 16 respectively, facing each other and firmly clamped around the outer mantle of the gun, and-provided with clampcounty of Philadelphia, and' Serial No. 622,322.

ing ears 17,`irmly held in place by means of bolts 18 and nuts 19 on topand below they gun bar-rel 10.

The ejector mechanism is arranged at the rear end of the gun and is encased in a housing 20 closed at its rear end by va lid 21 hingedlyv connected to the housing 20 as at 22 and within the housing 20, an ejector slide 23 is provided carrying the grenade or shell 24. This slide is provided with grooves 25 in its side walls near the bottom thereof with which it is guided within the casing or housing 20, the inner side walls of which are provided with suitable slats engaging the grooves 25.

To the bottom of the slide 23 a strap 38 is fastened, the end of which is guided over a drum 29 and a second drum 30 below the irst drum on the shaft of which a pinion 31 is arranged in mesh with a gear 32 and a crank shaft 33 journaled between the upper ends of standards 34 by means of which arrangement the ejector slide 23 can be drawn to the rear end of the housing 2O against the action of a number of springs. One of these springs 35, is arranged between a cross-head 36, sliding within a chamber 37 in the gun barrel, and the inner end face of the ejector slide 23 to which the cross-head is secured by means of straps 26 and 27.

Laterally disposed to the ejector slide in the housing 20 to both sides of the barrel are springs 40 and 41, sliding in housing 20 in which cross-heads 2S are disposed, to which one end of a strap 28 is secured, the other end of which is fastened to the bottom of slide 23, a groove 42 Within the bottom of the ejector carriage 23 is adapted to be engaged by the point 43 of a trigger rod 44 when the carriage is in its extreme rearward position. Between-the point 43 and the rod 44 the standard 45 for the rod 44 is provided with a chamber 46 within which a spring 47 is wound around the rod 44 between the point 43 and the. bottom of the chamber 46.

To the lower end of the rod 44 a cable 48 is attached, a pull on which relieves the trigger point 43 from its engagement in groove 42 of the ejector slide so that the saine under the action of the springs will be moved forward to eject the shell 24 into the barrel. At the mouth of the barrel a suitable seat 49 for a bomb 50 is provided which has a detonator at its point and a seat or anvil 51 at its rear'end aga-inst which the shell 24 strikes to throw the bomb.

It Will be clear that changes may be made in the general arrangement of myvdevice and the specific construction ot its details Without deviating from the scope or spirit of my invention.

What I claim as new and desire to secure by Letters Patent of the United States isl. A bomb thrower of the character described comprising a barrel having a seat for the bomb, an ejector slide at its opposite end, adapted to lire a shell to eject the bomb, means for normally holding said ejector slide in its rear position of rest, means for releasing said slide to fire the shell, and' means for guiding said slide back into its rear position read y lor firing after-each tiring operation. Y

2. A bomb thrower of the character described, comprising a barrel having a seat at its mouth for a bomb, a casing, an ejector slide within said casing, straps at the bottom of said slide, springs tending to impart to said slide a motion towards the mouth et the gun, means .tor winding said straps upon drums againstthe act-ion oi: said springs, means for holding said slide in its retracted position, and means for releasing said holding means to fire the shell against a bomb onsaid seat for throwing said bomb.

3. A bomb thrower of the character described coinprising a barrel, a seat at the front end of said barrel for a bomb, a housing at the opposite end of said barrel, an ejector slide slidably mounted within said housing, provided with a groove at its bottom, straps secured to said slide, a plu` ralitx,7 of drums for said straps, means for win ing said straps upon said drums, a plurality oi springs normally tending to move said slide forward, a means engaging the groove in the bottom of said slide to hold the same in retracted position against the act-ion of said springs, and means tor releasing said hold-ing means tomove said slide forward and to project shell on saidslide against a bomb on said seat ifor ejecting the same. Y

d. il bomb thrower ot the character described comprising` a'barrel, a seat near the mouth oit said barrel for a bomb to be thrown, a housing at the opposite end o t' said barrel, guides in said housing, an ejector slide adapted to` car 'a shell sliding along said guides and having a groove in its bottom, a plurality of springs normally 'tending to more said slide forward to pro` ject the shell, straps, secured to the bottom o. said slide` a plurality ot drums` a cra-nl( shatt tor "*taing said drums to wind the cables on s drums, a spring controlled trigger pin adapted to engage the groove in the bottom ol said slide tor holding the slide in its retracted position7 cable attached to the outer end oit said ain for eisengaging it from sic groove to allow a projection oit said slide by sai d si 4ings for projecting the shell from said sl ,de through the barrel z gainst the bomb on said 'seatv for throwing the same.

In bomb thrower ot the character described, av barrel, a seatftor a bomb on said barrel, an ejector slide at the opposite end ot said barrel, a cross-head sliding in said barrel, an ejector slide, bars securing said cross-head to said slide, a strong .spring be tween said cross-head and said slide', va plura-htjfv ot springs laterally disposed to said slide` normally tending to more' the same forward, means for holding said slide in its retracted position, against the action of said spring and means for releasing said-slide to project a shell therein against a bomb on said seat for throwing the same.
